What is wrong

In the event of a short circuit of a tool plugged into the onboard electrical socket, the GFPE breaker may not trip at the proper current before the user receives a shock.

Without proper protection against electrical shock, the user has a greater risk of injury.

Remedy

TSD will notify owners, and dealers will replace the breakers with GFCI breakers that will trip at a lower current, free of charge. The recall began on June 27, 2017. Owners may contact TSD Customer Service Department at 1‑800‑982‑8975. TSD's number for this recall is SN658.

What is wrong

Terex South Dakota (TSD) is recalling certain 2012-2017 Digger Derricks and Aerial Devices, models C4000, C5000, C6000, C7000, General, HR, OM, RM,RMX, SC, SCM, TC, TCX, TL, TM, and XT, built on Freightliner chassis with SmartPlex engine controls. The vehicles have a switch to monitor whether the hood is open or not.

Risk

If the hood switch prevents the remote engine controls from shutting the vehicle engine down in the event of a hydraulic issue on the Aerial or Digger Derrick, it may increase the risk of an injury.

Remedy

TSD will notify owners, and dealers will reprogram the vehicles to only disable the engine start function if the switch indicates that the hood is open, free of charge. The recall began on June 28, 2017. Owners may contact TSD Customer Service Department at 1‑800‑982‑8975. TSD's number for this recall is SN659.
